There is apparently an underground hidden faction of mortals magic-users in Mage the Assension, that is titled the "Maison Liban".
Them having the following origins:
An underground mystical order that largely consists of Sorcerers, Maison Liban has lineage that traces back to House Tremere. Following the destruction of House Deidne and the the betrayal of Goratrix, Mathieu de Calice left the order. De Calice, who was once an apprentice of Goratrix, lead his order of sorcerers into obscurity. Whilst the Tremere struggled with their new forms, Maison Liban focused their efforts on creating wards against divination in order to prevent their discovery.
The surviving members in modern nights are known for the paths of Counter Magic (Parma Magicka) Protection from Scrying and Divination, and Summoning Binding/Warding.
I understand why they did it and hid back then in the start - with the House Tremere eventually taking a "become undead or dead" approach to it's members, as well as the surviving mortal mages who defected being forced by the Order of Hermes into surveillance and into joining House Ex Miscellanea (presumably who became Maison Liban fleeing that too, out of respect/preservation for their own House's non-vampiric ways/practices or something like that)...but it's been centuries now.
The Order of Hermes and House - now Clan - Tremere have both got other, much bigger things to deal with right now and have diverged a lot since: so, it's not like the Maison Liban with it's knowledge of original Order/House ways is going to know any dangerous modern secrets.
So, based on what might be indicated by canon lore, is their anything that actually indicates whether them still hiding even in Modern Nights is actually even genuinley necessary anymore?
As in, if either of the factions they hide from found out about them, would there be any repercussions of that discovery? Or are the fears of the Maison Liban misplaced in the era of the 21st century?
