Xaiter Ikswon
They met when Xaiter was tasked to steal a map ffrom their party. They caught him sneaking near their campsite, but they ended up talking it out instead of fighting.
Taylor was very mistrustful of Xaiter, especially when Calle expressed interest in him very early on; but since he trusts her judgement of people, he tentatively allowed for Xaiter to travel with them.
Eventually they started getting on better terms, especially once Xaiter came clean about his original intentions and how those intentions changed because of Calle, but trouble struck.
They were investigating some sewers that were rumored to be haunted, and Taylor became possessed by the vengeful spirit that resided there. Taylor and Xaiter were scouting together when it happened, and the possessed Taylor turned his sword to Xaiter and nearly killed him. Eventually the others came, knocked out Taylor, but did not realize he had been possessed until the ghastly spirit rose from his body and attempted to attack them again.
The vengeful spirit was dealt with, but the ghosts it left behind was widely impactful. Taylor withdrew into himself for almost a month, terrified that his friends thought so little of him that he'd actually attack Xaiter, terrified that he'd become possessed and do it again.
Calle eventually got him to talk to her, but Xaiter and Taylor had stitled interactions for a while.
