To activate the Artefact of Transcendence requires immense power. Specifically, we need to infuse Balaur energy into the Activation Stone.

Also, Aetheric power that transcends time and space would be handy.
You can obtain [plur]Blue Balaur Scales occasionally by defeating Balaur in Reshanta.

They will infuse the necessary power into a Temporal Stone.

Go on, get to it! Those Blue Balaur Scales won’t collect themselves!
Then fetch some [plur]Blue Balaur Scales and take them to Maloren at the Kishar Observation Post.

Blue Balaur Scales are only found on highly ranked Balaur, like those guarding artefacts. If they can go toe-to-toe with you, Player, then you’re in the right place.

You can also check the Indratu Barracks in Heiron.

Or talk to Heiron’s general goods merchant Aririnirerk.

I just wanted to say good luck. We’re all counting on you, Player.

May Ariel’s protection go with you.
Back at last!

I've been waiting for you, Player, since I got Jucleas's order.

Did you bring the materials to imbue the Temporal Stone?
Didn’t Nani tell you anything?

You have to procure Blue Balaur Scales to empower a Temporal Stone.

Collect [plur]Blue Balaur Scales and take them to Maloren.

It’s not like you’re whipping up some biscuits! You’re changing reality!
(Casting a spell.) It’s time... or it will have been time... or wait. The grammar for time-travel descriptions is always suspect.

Well, that’s it. Take this Temporal Stone. The Artefact of Transcendence can return you to Dark Poeta.

If you have need to go back yet again, save yourself some grief and bring me the materials ahead of time.

I guess this is it. Faith and arms, Player!
