Again, the whole temple radiates magic. Nothing is currently radiating "more magic" than anything else. And, contrary to Stee's concerns, the plants appear to be just plants.
As Oliver looks through them, two of the plants look particularly interesting, as you knows they are ancient plants that are not known to exist anymore. You take a couple seedpods from each of the plants. One other plant has interesting leaves that you think might be useful for some alchemical efforts.
While Oliver walks directly into the garden area, Cords keeps a more considered approach and does not enter it, so much as walk around the perimeter to see what surprises you can hopefully not find.
Aizashi does not hear anyone or anything heading up the stairs. You do still hear shambling on the floor below, but they are not following up the stairs. More confident that you have not been followed up the stairs, you creep up to the edge and carefully take a look over the edge. You realize with dismay that you have accidentally worked your way around to the southern side of the temple and you can directly look down to where the orcs are! However, you are all being relatively quiet and the orcs are apparently not used to looking up frequently. As a result, you are confident you have not been seen. You do see several orcs working in their corner of the remnant. They are going into and out of the doors and buildings in that corner, but you can't see what they are doing, and the activity is not giving any obvious hints as to what they are doing.
Stee approaches the fountain. As you look into the fountain, you can confirm that the central pillar is covered in flowing water, so that the whole fountain has movement to the water, which has apparently prevented it from clouding up or getting stagnant. Inside the fountain, you see several water lilies floating on the top, and there are some small ornamental fishes swimming within. Despite the water's movement, the surface is remarkably still. You reach your cupped hand into the water to take a handful up to smell it. Nothing seems out of the ordinary, other than the ripples created by your hand and the drips from the water falling from your hand are always quickly quieted, which does not appear to be quite natural. That said, it appears to be nothing more than ordinary water to your senses.
Elyse joins Oliver in wandering through the garden, but instead of looking specifically at the plants, you are more focused on the area as a whole. Moving counter to Oliver, to cover more ground, your investigation comes to a quick halt when you trip over something unexpected. Quickly righting yourself, you see that you tripped on an arm that is lying on the ground behind a large planter.
