Eschaton: the launcher's real game shows through
Pemulis’s lobs can nail a coin on the baseline two out of three times off either side, is why it’s idiotic that he rushes the net so much instead of letting the other guy come in more.
Context
The Eschaton skill and the tennis skill are the same skill, and the narration can't help scoring the actual match while describing the game: Pemulis "can nail a coin on the baseline two out of three times off either side," a precision-lobber's weapon, "why it’s idiotic that he rushes the net so much." The greatest Eschaton player in E.T.A. history is great because his lob is great, and the tactical note about his real tennis (stop crowding the net, make the other guy come in) leaks right into the middle of the war-game. The body that aims the warhead is a body with an actual, critiquable serve-and-volley game.
