Not sure if Metorites would be considered as 'lore' but whatever.
My idea is that a meteorite strikes in middle of nowhere (not sure where, just not close to Salvus because I just read about a thread that says ther is a lot of RP in Salvus and it would make people go somewhere else) and once the lump of rock hits it will do devastating damage, will leave a huge crater in the ground with flames and such, and it will start thundering a lot.
Sorry, I have no other ideas, but the rock would be made out of some block that one could not find/obtain, like some sort of 'space rock' but it would be just obscidan. Some towns or something should have some houses collapsed due to the earthquake by the impact of the rock.
If you have any other ideas please suggest and maybe add some feedback!
EDIT: I am not sure if this event ready happened I wasn't around probably then I started playing late February on this server.
EDIT 2: Alphalord just suggested end stone as rock instead of obsidian because end stone is rare and seems like actual space rock (Because End seems to be like in space)
