[10] Tri-chess: a highly involved game of tri-dimensional chess played on a series of eight superimposed glassine boards. Pieces move not only horizontally, as in the ancient Persian game, but vertically as well. Two additional types of pieces are used in conjunction with the traditional "pawn, knight, bishop," et al. ... the "pilot," which may move in any direction horizontally or vertically until opposed by another piece, and the "ranger," which may move five vertical spaces and three horizontal, or vice versa, disregarding occupants of those squares.—Ed.
[11] Catooni: a Magogean woodland beast similar to the Virginia red-tailed deer, but with six legs and two sets of vestigial wings.—Ed.
[12] Goraru and sneri: wild beasts of Magog. The first is somewhat similar to the extinct "saber-toothed tiger" of Earth, except that it is equipped with a stony carapace; the second is a gigantic lizard with poisonous mobile horns.—Ed.
