Found one’s pride
The dead cannot be revived
The only path
Suffered in silence
Continued forward no matter the loss
Yet a way was found
Drowning in every drop
Stepped foot on the bridges of Sinnlos
A fearful and reckless conclusion
Became true partners
Remained sheltered from the reach of Nixi
It almost could have been
That is all he ever says
Hearts were eased with someone special
Created a miracle
Escaped the void and returned to light
Protecting what matters until the end
Persevered through all the hurt
Spirits were lifted together
The price one must pay
