Ctibor is always open to questions when online. If you need something from him offline you can reach him via email and he should respond in a timely manner.
Ctibor has been mudding off and on since 1991. Some friends of his introduced him to Avatar in the Fall of 1997, making his mudding more on than off. He joined the immortal ranks late in the year of 2006. While carrying out his immortal duties, he still stays an active player.
Centaurs are centaurs, not half creatures. Humans have the torso of a centaur and the legs of elves (ie half-centaurs) and horses have the body of a centaur and the head of a pegasus.
