I think the Krayt Dragon
would be an excellent addition to Tatooine, and a Krayt Event
centered around it would be interesting. If there were Krayt Pearl
rare loot drops, that had perhaps some enhanced crafting purpose, such as for an enhanced Color Crystal that has more than +41 to stats (maybe just a little extra +Endurance?), or a special high-end adrenal that provides 15 uses. Or a high-end set of Augment schematics that require a Krayt Pearl. These new schematics could be sold by the Krayt Event vendors.
There are some interesting factoids about Krayt Dragons
. Did you know it's suspected that they're descendants of Star Dragons
? Those dragons could fly in space!
There's an original thread
about the idea of a Krayt Dragon event.
