OK so I'm slightly cheating but I really need help on this riddle.

I am in a D&D based role play group and recently I uncovered a riddle hidden in some of blueprint documents the only information I have to work on all this is and I'm told no outside information in game is needed to solve it even if I can get a bit of a push it would be appreciated.

This riddle will lead you to the past,
It should be read both first and last,
The first will be the steps to take,
This steps will an answer make,
The word is "a-d.eckfl-i.ghjab" of this I vow,
When you see the path ahead,
Heed the warning that's here said,
Beware the deadly trials three,
Of there difficulty you'll soon agree,
Do not fear the coming price,
When you pass you'll arrive at paradise.
