I found the event rather uninteresting, i like that i could do all the quest with normal game play and the artwork was nice but none of the prizes really interested me so i wasn't motivated to do anything more, nor was i very engaged with it.
On my elvenar chapter city there was nothing of interest so i mainly went with the lowered kp option
and in my orc city there was some culture buildings to replace my faires culture but it wasnt a great boost and the pop buildings were worse than my dwarven level winter stars (per square), while i also got 2 of the orc ships they will most likely be replaced with orc nest once they come in crafting due to not having the early collect.
