aelwyn is also absolutely of the exact same mind about what to do with anyone stupid enough to steal the artifact. she would want to take the artifact and bring it back for study, but she'd also be 100% down with watching the punks suffer for their hubris and be both relieved and amused that someone else agrees.

alternatively, she's likely to have some trouble fighting (or more specifically trying to kill) the kelkies so she'd appreciate being helped
