Khalk is the letter K
There is no poem for khalk. It is a Northumbrian rune
Khalk (usually interpreted “cup” or “chalice) reversed indicates unfulfilled desires and longing. It is the cup of victory and attainment being emptied, possibly poured out, possibly spilled, maybe it has already been drunk, emptied to the dregs. There is no more to be had from this font, and now it is time to fill it again. Maybe something new, maybe something different, but there is no more to be had from this source, and seeking to quench your thirst from it will not satisfy, but instead leave you longing and unfulfilled.
