If you finish the quest, you will get the ability to claim white souls no matter what ending you took. The choice is either to get a companion (Aranea Ienith) or to be able to claim black souls as well as white souls. I chose black souls because I already have a good companion, and Aranea is not the best companion. Also, I am an avid enchanter. She is a mage who can cast Flame Atronach, which is the least powerful Atronach (She will also cast Frost Atronach if the enemy is resistant or immune to fire), but the upside is that she can use Ice Storm on a group of enemies. She will use spells like Lightning Bolt and Ice Spike, and at the beggining of every fight, Oakflesh. I guess if you want a mage companion at a low level, then you should choose to give the star to Aranea. If you have no need for a follower like Aranea, then you should definetely choose to give it to Nelacar. Just to confirm, Aranea is available as a companion, and The Black Star can hold both white souls (whatever size), and black souls (always Grand), so it is really up to you.
