Symbols

Other than familiars for attacking and other random uses, there are also familiars which act as fortresses, which are refered to as Symbols. Unlike other familiars, Symbols are being 'advented' by mana collecting familiars rather than being summoned in the usual way. It normally requires a certain rune to be leveled up to a certain level before familiars can build up Symbols.

Just like Sanctuaries, the type of Symbols differ from each tree of magic, and each be given a different name.
