His master is SEATH (sorta). After you kill Freja (who drops Seath's soul) he says "What skill. You've defeated my master. But our master never dies, only changes form, so that he may seethe for all eternity..."

SO aside from the parallels previously mentioned, ​​​​​​it's pretty much confirmed that Tark's creator was... Seath (or more likely the soul of Seath). He said his master created him a loooong time ago, so it is possible Seath created him and Tark saw Seath's soul rise again, considering that it seems like he has seen more than one iteration of Seath's soul, but we can't know that for sure.
