have you done the deal?

I once met a flower looking creature,
a dark volgur being with intense facial features,
a skilled investor,
who's met every ancestor,
if he comes for a deal it has already begun,
as people of previous was swayed by the words from his tongue,
he promises something truly astounding,
for a negative change in your surroundings,
the wish ends with you but the change is constant,
so whatever you chose should be quite significant,
because of the past people's permanent it might look like a curse,
perhaps you change the absolute that made your world worse,
use this wish,
and walk in ignorant bliss,
do not dwell,
on the world your about to sell,
and always act blind,
towards the next generation with what you left behind,
