Essence of Breidablik
*You gain an artifact similar to Breidablik a handgun like device which can be used to summon heroes from the Fire Emblem multiverse. You also get enough orbs a day to do at least one summoning. Unlike the original Breidablik this one can summon groups of generic soldiers, mages, manaketes, and other rank and file you could find in Fire Emblem. Additionally you can be specific when summoning by focusing on the particular individual you want even if they were not originally summonable as long as they are of the Fire Emblem setting.
*Gain a massive castle that has enough space for all of the heroes you may summon though it is a bit run down. The castle can sit in the Outrealms or be dropped onto the physical plane wherever you require it by summoning it with the Breidablik. It takes at least a day to relocate or store it away after it is used.
*Can find gates that let you travel to different worlds in the Fire Emblem multiverse and have explicit control over whether they remain active or shut down from either side.
*Optionally can be transported to the start of any one Fire Emblem game in a position to insert yourself within the ranks of the protagonists without too many questions.
*Complimentary hooded robes in a color of your choice, defaults to white and gold.
