This guide is suitable for current RuneScape and Old School.
Search the fire remains in order to begin the quest.
Using the map at the top of this guide, make your way to Islwyn and Eluned and speak with both of them in whatever order you desire. They will tell you to go to Glarial's Tomb and retrieve a consecration seed.
Hint: If you do not talk to them within five minutes of searching the fire remains, they will leave their spot but return.
Head to Glarial's Tomb, located west of the Fishing Guild. Go inside of it and defeat the level 84 moss giant unarmed and without prayer. This includes any runes and arrows. Make sure you bring plenty of food. Pick up the consecration seed it drops and return to the elves in Tirannwn.
Talk to Eluned. Hand over the consecration seed and she will sing into it, infusing it with a special property. She will give it back and ask that you place it at Glarial's grave inside of the waterfall.
Make sure that you have Glarial's amulet equipped, as well as the seed, a rope, and a spade in your inventory. Enter the waterfall and go into the east room. Search through the crates until you find a key. Back-track and now head into the west room, where you can use your key on the door and the door after that. Plant the seed near Glarial's grave and a small crystal tree will appear. Go into the ground.
Go back to the two elves and tell them of what happened.
Congratulations! Quest Complete!
