Sarah's (un)timely death isn't that much of a shock.

Then rose the King and moved his host by night
And ever pushed Sir Mordred, league by league,
Back to the sunset bound of Lyonesse—
A land of old upheaven from the abyss
By fire, to sink into the abyss again;
Where fragments of forgotten peoples dwelt,
And the long mountains ended in a coast
Of ever-shifting sand, and far away
The phantom circle of a moaning sea.
~Alfred, Lord Tennyson
In sea-cold Lyonesse,
When the Sabbath eve shafts down
On the roofs, walls, belfries
Of the foundered town,
The Nereids pluck their lyres
Where the green translucency beats,
And with motionless eyes at gaze
Make ministrely in the streets./
And the ocean water stirs
In salt-worn casemant and porch
Plies the blunt-nosed fish
With fire in his skull for torch.
And the ringing wires resound;
And the unearthly lovely weep,
In lament of the music they make
In the sullen courts of sleep:
Whose marble flowers bloom for aye:
And—lapped by the moon-guiled tide—
Mock their carver with heart of stone,
Caged in his stone-ribbed side.
~ Walter de la Mare
