This is a newer Ragnarok Onling private server that prides itself on having a great, friendly community. The GM's are the friendliest you can find, and they always welcome players that are new to Ragnarok. It may be small right now, but it is growing greatly. Here's some info on it.

DeliriumRO (dRO for short) is a private server based on the Ragnarok Online software. It runs on the eAthena emulator, stable SVN. Delirium Domini was born on March 4, 2006. It was founded by Hassan and Uindi (more commonly known as Epyon) -- and after being up for six months, the site's traffic was decent. Being a huge fan of RO and having been on failed servers for too long, Uindi decided to start a serious RO server -- using the site's name for it. Thus, DeliriumRO was born.
