Welp, my Google skills have failed me. There was an event in 2009, the name of which I am uncertain, which culminated in the shattering of what was known as a Blood Sigil. A lot of red crystal shards fell to the ground, to be freely picked up by whomever was present. I missed this event entirely. I know this event happened on Siege, because I saw quite a lot of them adorning the staircase of Famine's Museum. I suppose the ones I remembered seeing might be different than the event that Google coughed up for me. In any case - I am looking for the name of those shards, and am looking to buy or trade for one. Thanks!
