Eternal Non-life

These days, the Ghoul Volga has been wrecking havoc around the city. This is a time when wizards in the city should be doing their job. Though my abilities aren't much, I can still do something, but I need your help.
The 'Ring of No Life,' a symbol of eternal life lies in the body of Volga, and this makes him rise from the dead. I need magic to remove the ring. Please, get <HFFFA7272>4 Horns<HFFFFFFFF> for me. I need the power from the horns to start this magic. You can get them by using your <HFFFA7272>Collecting Skill<HFFFFFFFF> on <HFFFA7272>Gargoyles<HFFFFFFFF> in <HFFFA7272>Nocturn Yard<HFFFFFFFF>.

Please bring <HFFFA7272>4 Horns<HFFFFFFFF> for the magic to destroy Volga. You can get them by using your <HFFFA7272>Collecting Skill<HFFFFFFFF> on <HFFFA7272>Gargoyles<HFFFFFFFF> in <HFFFA7272>Nocturn Yard<HFFFFFFFF>. Please, do this as soon as possible!

We're almost running out of time, but the Horns you took will be very helpful. Well done!
