You get the Egyptian blue lily from the blue nile falls Then you go back to the town Nabooti and trade the flower for a desert turban from the lady at the market stalls.
In my opinion tomb raider underworld is much better than tomb raider legend because you learn alot more about Lara in this one especcially because her devotion to finding her mother is much more...
Yep there is a game called beneath the ashes and there is one called Lara's shadow but they are add-ons, there is one called Lara croft and the guardian of light which is a proper games, not a add-on...
