One of those things that is best left a legend or an exaggeration. Well described, but unless one is playing out ragnarock, it seems it is likely to remain in the maelstrom.
Perhaps someone could find a way to connect with the spear though the ether, creating linkages only strong enough that the being could draw power from the spear without physically touching it. L’ruhk’s fragment would not like this and may seek 'help' using similar means to stop this leeching... Go to Comment
A PC Conjurer or summoner, basically any mage whose sole purpose in life is summoning creatures to aid in battles and various situations, is cursed with a hex, and needs to find a way to undo the curse...before he goes mad, or his fellow PCs throw him out of the party, or worse.
Everything he/she summons, never goes away. So you'll have to figure out what the heck to do with that dire bear or fire elemental once it's done fighting the orcs for you. Eventually a caravan of bizarre creatures either annoyingly ends up following the summoner around, or they go off to cause mayhem elsewhere. Bad news for the poor spell-caster regardless.
