Tristan

Father Tristan is a human cleric at the Temple of Sarenrae in Emon. As an NPC, he is played by Matthew Mercer.

Before the Stream
When Pike was killed during a fight with Jurazel the glabrezu, Vox Machina brought her body to the temple and asked Father Tristan to perform a resurrection ritual. With their well-trained clerics and contributions to the ritual by party members, Father Tristan succeeded in bringing Pike back to life.

The Briarwoods
In, when Vax'ildan was nearly killed by the Briarwoods and was feeling the effects of a vampire bite, Vox Machina returned to the Temple of Sarenrae. There they met Father Tristan again, who disinfected Vax's wounds and agreed to sanctify the water in Tiberius's Decanter of Endless Water, a process that took several days.

In, when Vax bought supplies for Vox Machina in the temple to help them combat vampires, he also asked for a holy symbol of Sarenrae. Tristan gave one to him, and Vax commented that reminded him of his friend (Pike).
