Firstly it was used again in lore for felwinter. Secondly we destroyed to siva replication chamber and purged almost all of its remains. Thirdly alot of what neomuna was and still is built out of is a version of siva that has been advance a few thousand years. Lastly ur bad and haha (Sorry this comment seemed alot more negative and potentually wrong than I thought it would. Hence why I added the Ur bad and haha part, it was sarcasim but sarcasim is hard to understand through text.) How ever I too would like to see siva again... Why did I type out this long -blam!- comment... because I am cooling down after a bad checkmate experience
