[Lore Question] The floating red crystals surrounding the starter towns

[Kitab al-Azif]

Surrounding the starter towns of Holtburg, Shoushi, and Yaraq is a ring of floating red crystals. These crystals hover over craters in the earth, giving the impression that they rose from the ground in a manner similar to the shadow spires.

I know that their real, metagame purpose is to provide a visual border between n00b hunting areas and higher level hunting areas, but what's the in-game lore rational for their existence? Didn't they show up during Gaerlan's story arc?

cant really recall but i think it was explained like this

someone raised them up as a 'barrier to protect newcomers to dereth' so now powerful creatures(high lvl) will come inside the areas or something(nothing high level will spawn within them...)

it was close to the start of the garlain story arc, and nuhmidera (sp) is the one that supposidly raised them around the three remaining starter towns (btw, this was also when all the other starter towns were attacked) Martin was under the control of Garlain and was attacking the starter side towns and planning an attack on the queens young son.
