Trill

Trill was the pet wyvern of Mattias Farseer. Mattias found Trill as a fledgling after he had killed her mother. He adopted the little wyvern and the two travelled together for many years. They found that due to Trill's nature as a wyvern, they had to continually move farther south, away from the more settled regions of northern Faerûn. Mattias and Trill joined Corvus Nightfeather's Circus of Wonders and were a featured act. Trill died in 1479 DR at the side of his master, fighting together against a demon in the Plain of Stone Spiders.

Trill was well behaved for a wyvern and didn't attack humans or other creatures without provocation.
