So the 1st question is should we capitalize Atrium and Ruins? I suppose, the Ruins are the name for those specific Ruins, not just any ruins, right? We do not capitalize other biomes/mobs because... um... for ex., werepig is not a name. But if you say the Atrium, it'll mean that this location is unique.
Question #2. Do you pronounce Star-sky (Hutch's fishbowl) as [star-skee] or [star-skuy]? I know how to pronounce sky, but, as I know, there was a reference to "Starsky and Hutch" tv show, in which Starsky was pronounced as [starskee].
