The Rising Event - Lore Discussion

[Alberel]

The added verse that the minstrel gave us is as follows:

A growing light o'er all the realm
Fingers bright on highlands white
in an instance, a blade that smites the night.
But ill winds rise as the great gate yawns
Hope rides to meet what naught can cheat
an old despair astride a new-shod mare.

The first line would appear to describe the growing power of the Warriors of Light.
The second is a reference to Coerthas, though I have no idea what 'fingers bright' may mean.
The 'blade that smites the night' would most likely be the blade of light we used to defeat Lahabrea, though it's possible that this refers to Shiva as we know she uses a sword based on the few teases we've seen.
The 'great gate' is almost certainly the gates of Ishgard.
'What naught can cheat' would be death in my best interpretation.
It is my guess that the 'old despair' is Lahabrea; his 'new-shod mare' being his new host body.
