↑The Gates of Tagmeth, "Chapter II: Departure", V — " 'Erim, Quill, Rue, and what’s-his-name, oh yes, Killy, are now five-commanders.' "
↑To Ride a Rathorn, "Chapter X: Battles Old and New", II — "The day's first class—archery with a Jaran ten—passed without incident, except for Erim hitting the mark every time. His aim was indeed very good, almost uncanny, for someone who looked as if he shot at random from a truly awful pose."
↑To Ride a Rathorn, "Chapter XII: Unsheathed", II — "(except for Erim's, who couldn't seem to miss if he tried)"
↑To Ride a Rathorn, "Chapter XX: The Bear Pit", III — "During archery practice, as an experiment, they blindfolded Erim and spun him around until he wobbled like a drunkard.

↑To Ride a Rathorn, "Chapter IX: School Days", I — "Vant was always finding fault with one or another of them, for example when Erim tripped over his own feet and more or less threw a bowl of soup in Vant's face (Jame wondered about that: Erim might be clumsy, but he had very good aim),"
