Tales of Tolgard
Talking owls exactly resemble large but ordinary owls until they speak. These magical beasts can speak Common, Celestial, Elven, and up to four other languages. Talking owls are two feet high with a six foot wingspan.
Talking owls exist to serve as advisers for champions of good such as paladins. As such, they are highly intelligent and knowledgeable as well as very wise. Typically, a talking owl will test a good-aligned individual or party before offering its aid by feigning a broken wing or other injury to see how they treat it. A talking owl may also consent to serve as a familiar for a good-aligned wizard or sorcerer.
Talking owls are not strong in combat and avoid it whenever possible. A talking owl would much rather seek aid from other good-aligned creatures than fight itself.
