The in-game descriptions of the Mask of the Sealer and the Remedy sorcery speak of two other Sealers aside from Ingward who abandoned their duty to watch over the Seal of New Londo. One Sealer, Yulva, is said in the Remedy description to have gone to Blighttown to cure the sick. It can be speculated the corpse where the Crimson Set, Tin Banishment Catalyst and Remedy spell, all of which would be associated with a Sealer, is her.

The second is unnamed, but there is only one other male NPC in the game who wears the complete Sealer set, sans the mask. It is worth noting that the Mask of the Sealer was a "symbol of their resolve", which he would lack had he abandoned his duty. In Anor Londo when confronting Lautrec with the Black Eye Orb, he can be seen assisting Lautrec as a White Phantom. Seeing as Phantoms exist outside of the player's true timeline, it is unclear whether or not the man remains alive in the game's present.
