Lament of the Wishing Well

Come to me with your shiny tokens -
Your precious dreams envisaged then spoken
In watery echo, ripple out each request;
Your aquatic genii: servile to behest.

But I was once worshipped, revered, adored,
Sacrament, sacrosanct, both pauper and lord,
Now I am contained and serving others -
Resort for the desperate, greedy, and lovers.
