The Elves' Riddle

Okay. So, this is where I am in my writing: Dakota and her group of people are outside the gates of Polarya, the elven kingdom. (Is the name Polarya a little too weird? It's pronounced Poh-lar-ee-yuh) To get inside, they must solve a riddle. Problem is, I can't think of a riddle! :) Here's the poem that is on the gates:

Many beings seek us out

Believing their motives are wise.

But we, as a people, have many doubts

As to whether they're wanting a prize.

If you, traveling strangers, can solve this next rhyme,

Within the next hour or two,

We'll let you come in and spend here some time,

If not, we will come there for you.

I hope it doesn't sound too cheesy. I mean, the elves are supposed to be these wise, strong creatures that are experts at practically everything relating to arts, you know, writing, music, poetry. I'm not that good at poetry, sooo....

But anyway, the next riddle has to rhyme, according to the first line of the second section. I wish it didn't have to, but I couldn't think of anything else to say for the poem. :)

I'm drawing a blank as to what to say for the riddle, so I'm open to any suggestions, comments, concerns, or your riddles! Remember it has to be wise-sounding. Sort of. Elvish. :)
