The X20 Mod is intended to bring the design philosophy of the Vampire tabletop RPG's 20th Anniversary Editions to Bloodlines: to make it feel like it fits into the wider World of Darkness setting by including references both overt and subtle, obvious and deep-dive, referencing material that came out before Bloodlines and after. One of Clan Quest Mod's recommended mods!
The twin-snake design is the AURYN from The Neverending Story. Replaced it with something a little less infringing: the three-snake logo of the Vampire: The Eternal Struggle card game.
