Not to be given to Dark Avengers' Panthers is a reference to an in-clan RP event where Jhaelle was carrying a plushie that she'd made to resemble Amathal.

Quoted from the synopsis of the event on the forums:

At first they chatted idly, much of the conversation directed toward the stuffed likeness of Amathal that Jhaelle carried. The stuffed toy caught the interest of Allana's panther also, who remained intently beside the dwarf in the chance Jhaelle might gift the toy. The dwarf did not give the doll to the great beast, instead she gave it a different one, this one resembling the man Jevin. Max, pleased with his new toy, retreated to the corner of the room near Allana and remained there squeaking the new stuffed thing for the remainder of the meeting.
