You will spawn at the base of the mountains that will lead you to a woodland mansion at coordinates 750, 250, if you travel to the east. There are two secret rooms inside the building that contain two protected chests by TNT. You can find them at coordinates 763, 68, 281 and 776, 68, 285. Both chests contain Ender Pearls.
These pearls can be used for teleportation or for crafting Eye of Ender, if you're looking forward to building an End portal.
