Poetic Summary of King Arthur Book "Balyn and Balan". Honest opinions, please!?

[Samantha]

Old King Ryon’s barbaric threat
A possible army’s fierce onset
Irate Arthur upon hearing
Until come a strange woman nearing

A Great sword offered to the pure
Many try, none procure
Sir Balyn draws from the sheath
The lady does not wish of it to bequeath

Embittered, she wishes Balyn’s demise
For to murder, only himself complies
Slain, she fell and nothing more
And of him, King Arthur did then abhor

To earn back his repute with the king
Balyn journeyed to Ryon then vowing
Arthur’s great foe would be killed
And Balyn’s glory would be fulfilled

Soon after departure he soon meets
Another knight whom he then defeats
Though without meaning he takes another life
For he slain not only the man, but also his wife

Balan, his brother then arrives
The two of whom go on to contrive
To travel together, until appears
Wizardly Merlin, the great old seer
Prophecy made, that Balyn will bring much loss
‘til a saddened knight they come across
Who spoke of his death at Garlon’s sword
Cruel Garlon’s death they calmly assured

Balyn goes on to attend a feast
Where not soon after, Garlon is deceased
King Pelles angered of the death of one of his knights
Attacks Balyn, for with whom he fights

Once unarmed Balyn sees the mystical Grail
And can think of little but to King Pelles impale
With a great spear he wields against Pelles’ rule he broke
And cast upon the locality the Dolorous Stroke

Riding through the destruction, another knight lent
A shield to Balyn, for two deaths would soon advent
Another knight nears, soon both have perished
Buried as brothers, their last miens anguished
