title: Mercere Portals
---
# Introduction
A common question is how easily the redcaps travel. In particular,
where do they have Mercere Portals? Some are mentioned in canon, but
they are scattered across many books, and it is hard to find them all.
There has been one effort by Argentius to map all the
[Mercere Portals](https://lexhermetica.wordpress.com/2021/01/09/maps-of-the-order-of-hermes-portal-network/).
Personally, I prefer the map of canon portals.
This means that redcaps in many tribunals have to use mundane means to
travel to the next tribunal. For instance, in Hibernia, redcaps from
Leth Moga could go by ship to Bretagne and use the portal via Durenmar
to Harco. Redcaps from Leth Cuinn could go to Coventry to relay
messages or use the portal to Harco.
I would possibly add Mercere Portals from Harco to Iberia and
Thebes, which are disconnected and riddled with great distances
in the strictly canon map. They are stable covenants, making it
relatively safe to set up links.
The more speculative map means that travel and messaging is much more
efficient, somewhat breaking the medieval feel. The redcap travelling
vast distances by mundane means becomes a lot less common.
It is unclear which portals are available to whom.
The portals through Durenmar can be used freely by magi at master rank
or above, and by redcaps. Everybody else pays a fee of 2p per person,
but a small entourage can be brought for free [GotF:26].
According to [HoH:TL:89], magi who build portals appoints a gatekeeper
to decide who may pass or not.
The customary toll is 1pvf/person, with no mention of an entourage.
Redcaps and others in direct service to the order do not pay.
It is reasonable to think that there is a difference between the
portals built before and after the Schism.
Note that [ToH:R:66] lists many more portals from Harco than the ones that
Argentius has on his map. These are tightly controlled though, and
can be used only by redcaps and for emergencies.
# The Hermes Portal of 3rd and 4th edition
Using previous editions, it is important to note that the Mercere Portals
used to be Hermes Portals, which then had permanent duration and was
available to anyone with sufficient knowledge of the arts to learn the
spell.
The Mercere Portals as a House Secret is a 5ed invention.
The large number of portals in the Greater Alps, with covenants linking
its chapter houses, is hardly justified in 5ed. The vis cost would
be prohibitive.
Therefore, each portal mentioned in [SoI] should be reconsidered, to
decide if it is a Mercere Portal, or just a Hermes Portal which has
excited for a certain period and may or may not have been renewed.
The canon map only lists those which have been explicitly named.
# Suggested interpretation
## The Durenmar Network
Constructed in the early years of the Order,
these links are well known to exist between Durenmar
and each of the other Houses' covenants, i.e. from Durenmar to
+ Crintera (Bjornar)
+ Harco (Mercere)
+ Verdi (Verditius)
+ Magvillus (Guernicus)
+ Fudarus (Tytalus)
+ Lycaneon (Tremere - original covenant)
+ Valnastium (Jerbiton)
+ Irencillia (Merinita)
+ Cave of the Twisting Shadows (Criamon)
+ Val Negra (now defunct)
Any magus turning up to travel will normally be permitted through
for the toll of 2p per magus including his entourage.
Archmagi, masters and those of equivalent reputation, redcaps, and
quaesitores on official business are allowed through.
## The Harco Network
This network is also widely known to exist, even though
exact destinations may be unknown. It is managed by House
Mercere to fascilitate easy messaging across the Order.
Some of the links are ancient, and some have been created after
the Schism War.
Harco has portals to
+ Mercere House in Coventry (Stonehenge)
+ Durenmar (which is managed under the Durenmar network)
+ Lycaneon [AtD]
+ Cunfin in France
+ Venice [ToH:R:66]
+ Barcelona (Iberia) *non-canon*
+ A small tower North of Madrid (Iberia) [ToH:R:66]
+ Alexandria, the Mercere Covenant in Thebes *non-canon*
+ Circulus Ruber [ToH:R:66] *destroyed in the Schism War*
The Mercere and the Quaesitores are normally allowed to use these
links for free.
Others are sometimes allowed to use them, but the redcaps
are reluctant to allow free passage for fear that it may damage
their trade businesses.
When people are allowed to travel, the charge is 1p/person, and
heavy tariffs are applied to any good carried through.
These tariffs also apply to the Durenmar link.
By 3ed [ToH:R], there should be more portals, while 5ed encourages
a troupe decision.
a troupe decision. It seems reasonable to assume that the border
regions in Hibernia, Loch Leglean, Novgorod, and the Levant are considered
to risky to have portals.
## Private Portals
These portals link a covenant to its Chapter Houses.
They are rarely known outside the controlling covenant and the
redcaps. Generally, they are only available to invited guests,
including redcaps.
+ Cirque du Gavernie - Aedes Mercuri [F&F]
+ Cirque du Gavernie - Barcelona [F&F] *defunct*
+ Valnastium - Konstanz [SoI]
+ Valnastium - Vienna [SoI]
The two Valnastium links are much used by travelling Jerbiton,
who use them for free as guests at the Domus Magnus.
Since Valnastium is not short on vis, they have little incentive
to grant access to others.
## Other Portals
These portals are funded primarily by tolls, with the standard rate
being 1p per person.
All travel is at the sole discression of the custodian, as is the charging
for the toll.
The custodian keeps 10% of the fee, and thus has an incentive to allow
travel.
Redcaps and quaesitores on official business are normally let through for
free.
These portals are not very well known, and a local Area Lore+Int roll of 9+
is needed to know about them.
+ Magvillus - Covenant of the Icy North [SoI]
Magvillus as the Domus Magnus of Guernicus enjoys the trust
which have let the Mercere install a portal.
The annual Midsummer Fair at the Icy North also makes it a lucrative
business.
+ Verdi - Venice [ToH:R]
+ Rellantali - Venice [ToH:R:86]
Roman covenants are short on vis, and therefore very happy to let
travellers use their links and charge the toll.
## Canon Hermes Portals
These links are expensive to maintain.
+ Leczyka - Three Lakes [DotB]
This is a post-Schism link, as one of the creating magi is currently
alive at 133. However, this assumes a Hermes Portal.
Its existence is a well-guarded secret.
The vast distances and availability of vis may justify its being
renewed anually.
