Guys, did we notice how the servants in Norse mythology always come in a group of two, either as a couple or siblings, like Thjalfi and Roskva! Now..
A bit of info!! ✨
Fimafeng meaning "hurrying service" was praised by the god's during the feast in Lokasenna, for being good job at welcoming guests and serving them! Sadly, he is killed out of jealousy by Loki at a party held by his master, after hearing him being lauded by the people for the banquet he had prepared to the Æsir.
Eldir meaning "fire-stoker" is Ægir's servant and outer guardian/herdsman. He too was praised during the feast for his behavior but was lucky to not have been slain. He was the first verbal opponent in the poem, personally keeping Loki out of the hall after he got kicked out and informed Loki what they were talking!
Personal interpretations! ✨
Personally, Fimafeng is giving me the "Sunshine, perfect beloved boy, could do no wrong" vibes, kinda like Baldr and is like.. not at all annoying just super sweet and humble! While Eldir is giving the "intimidating in appearance, but the softest, sweetest man alive!" just because he stands at the entrance and keeps up with Loki's drunken crap, even though he just killed someone Eldir most likely cares about! Also the fact he informs Loki about what they're saying.. He just feels a little blunt and honest!
