Into Hell's Maw
The Riverhunt Ruins and Netherbox is a joint project between KedNys and jchance.
Ked built the ruins above in the mid 1400s, before computers were invented. Special care was to give a dilapidated and overgrown appearance and the entire area was terraformed by hand including the deep pond in the center.
Jchance built the "netherbox" below. Over 30 hours of placing netherrack by hand and countless (and sometimes hilarious) mod requests for fire and lava.
The combined project gives a haunting presentation and makes you feel like you're actually walking through a ruined ancient city and in to the forbidden temple with a gateway to hell.
