His face doesn't have the obvious projection of a dog muzzle, and is described as flat with a broad nose with black nostrils. He has sharp ears, both laying back against his scalp and eyes wide apart.
One of his forearms looked almost withered and he held it close to his chest.
In 2040, the relationship between trolls and humans came to a tipping point. After many incidents and maltreatments from humans, trolls started to leave the Earths with a human presence in it and found refuge on Earth West 1,617,524.
The captives were brought to Earth West 1,617,524 as a present to their ruler, the Granddaughter Petra. The humans, playing for time, said they could provide the beagles with more ray guns and were spared.
After their audience with Petra, Sally and Monica were brought to one end of the palace with a large communal area with central hearth and small chambers that would serve as their living quarters for the duration of their captivity.
Brian, at the time Petra's adviser, took that opportunity to invite them to have dinner with him and had food that kobolds selected before prepared for them. He told them that he was considered strange for a beagle because his nose follow strange scents and was tolerated by Petra only because that proved himself useful from time to time.
The three of them discussed about the beagles' society, religion and asked questions about various aspects of the human world.
Brian, being one of the most humanized of the local beagles, is one of the main contacts to the team of human researchers who came to study them after the first contact in 2040.
He possesses a print of "Dogs Playing Poker" that has been given to him as a gift from Sally Linsay since she thought it was a good joke.
