This is adapted from the poem All That is Gold Does Not Glitter. Found it quite easy to make it apply to Shen.
Jewels are not all that do glitter,
So too does the vision of loss.
And so Shen doth set forth from his home,
To lands both in heat and in frost.
Over time he doth look withered,
Yet age does not keep him at bay.
Dirgest must be found, he must be bound,
For his crimes the demon must pay.
Trickster or not Shen has woken,
He travels from autumn to spring.
Summer and winter, across the land,
To find this one shining thing.
And he shall never be broken,
Wives, mead and wine he shall taste.
Dirgest cannot escape him forever,
The trickster's wrath he shall face.
