Telir Thumble was a Wood Elf, raised in a monastery as a monk. He was sponsored by the Thumble family, and while he had never met Trant Thumble, Telir was sure he was super nice. Telir was a very poetic man, and was very fond of wishing people "Happy Namasday." Telir also recently had his 100th birthday, becoming a man amongst his people.
Telir accompanied Rhavar, Temerity Barakas, and Steve Meloncamp on a mission to bring the Demonomicon, to Fennekin, though they failed when Steve absconded with it through a portal. Telir's fate is unknown.
