Quote from Eureka story:

"Hmm... It occurs to me that no one bothered to tell you the name of the island we mean to explore. Am I correct? It's a bit grandiose and melodramatic, but we've tentatively named it for a place from Allagan legend. A forbidden land where fearsome weapons were hidden away for safekeeping... We call it...Eureka." - Krile Mayer Baldesion

So it seems like this is linked to the "original" Eureka.
