Unfortunately, there wasn't much else of interest. There were no giant armouries with magical weaponry, which Erik was okay with since he preferred making his own weapons anyway, nor were there any 'get-strong-quick' machines.
It seemed that the biggest benefits of this space were its extensive library and the transference core. Technically, there was the isolation and secrecy aspect as well, but Erik's dimension was already able to fill that role.
Perhaps it wasn't too surprising. Lemayian did talk about this city as a centre of study and learning for advancing Ymir and Audumla's experiments, not as a military bulwark.
Still, that didn't mean there wasn't anything else of interest. There were crafting areas and training rooms, for example… but they weren't as good as the ones Erik had in his dimension.
