Gid cannot be too powerful. A time-traveler with the ability to freely change the past would not allow himself to be shot and lose a leg, for example. I don't think he can consciously warp reality enough to account for Cassie's address changes, for the same reason. Still, he is very capable:<br>
<br>1) He's strong, since he can break through a door with one lunge (p. 82).<br>2) He's agile, since he can do professional-level dancing even after losing a leg.<br>3) He has a time-sense, though there are places it doesn't work (p. 75). Perhaps when he's in space?<br>
4) He may have matured more quickly than usual, allowing him to appear older than he really is.<br>5) He has a remarkable range of knowledge, including physics, Earth arcana, and old sea shanties.<br>6) He can enter a locked room through a one-foot-square hole.<br>
<br>I think these can be accounted for by two factors: his biological father and his adoptive father. I think we should believe he was born on Woldercan. Ambassador Klauser saw him there as a young boy (p. 297). Klauser also says that Wolder males try to seduce Earth females, and Chase tells us that they can reproduce with other species. This probably accounts for his physicial traits.<br>
<br>His adoptive father is Robert Chase, who seems to have known Lovecraft (p. 75). If Lovecraft used him as the basis for his stories of Randolph Carter, we know that he is an "old dreamer" (Dream Quest of the Unknown Kadath) who is well-aquainted with the mysterious beings of Earth (who are aliens, at least in this novel). Bob Chase was either an old wizard who had some means of prolonging his life, or a time-traveler. He probably taught his son a great deal.<br>
<br>There is also the connection to Charles Finney and the "Circus of Dr. Lao" to account for. Bob Chase became the first ambassador to Woldercan. Is it too much to speculate that he used some knowlege he gained through his arcane research to get a clue to the planet's location from the old space-faring races that are hidden on Earth? He may have collaborated with Chuck Finney, a descendant of the Charles Finney who wrote a novel based on his encounter with Dr. Lao and his circus, in order to get the planet discovered. Lao himself may have come from the planet Woldercan, and brought some of the humanoid-animal crossbreed monsters from there (there was a centaur in his circus, for example).<br>
