Found a secret that I don't know how to solve...

[akmount]

In the secret fight against the druid and the owl, in a new patch he now drops a book with a riddle that reads:

'Within the PYRAMID lies the chamber of DREAMS'
'Within the CHAMBER lies a pool of clear WATER'
'Within the WATER lies a secret...'
'But only those who wield the ELECTRIC magic of the Druids may find it.'

This could be a troll, or a possible clue to a secret that I don't know how. Anyone know how to solve it?
