Got it. So it is more like induction based or their experience. But if I knew it as a player I wouldn't need the spell, so if I get it right, it is up to you as a DM to decide if to reveal something I don't know as a player, but might have known (with great insight) as the PC. Right?
About the time of the conjuration - after we sum up with the group the divination stuff.
About conjuring, maybe it is different for wizards:

It says: "The caster need not fear that the elemental force summoned will turn on him, so concentration upon the activities of the fire elemental (or other creatures summoned) or protection from the creature is not necessary."
"The fire elemental or other creature summoned remains for a maximum of one turn per level of the caster"
It says the range of the spell is 80 yards but doesn't say anything about what happens if the elemental is out of this range. I think a fair interpretation is that the elemental appears within 80 yards range but then can move farther for the duration of the spell.
One can also learn this is the meaning from the spell:
https://adnd2e.fandom.com/wiki/Aerial_S ... est_Spell)
There the range is 10 yards and the servant is called for 1d/level and almost specifically to fetch someone or something, so it is not logical to say he will disappear if he goes farther than 10 yards from the caster. (in that spell you do have to cast protection from evil and the servant may want to kill you...)
Also, 65% 12 HD, 20% 16HD, 9% 2-4 salamanders, 4% efreeti, 2% 21-24 HD. So efreeti may grant wish
(and Ke'Sha would wish to have unintelligent vampire under his control
)
with stone of controlling earth elementals:
DMG wrote:Stone of Controlling Earth Elementals: A stone of this nature is typically an oddly
shaped bit of roughly polished rock. The possessor of such a stone need but utter a single
command word, and an earth elemental of 12-Hit-Dice size will come to the summoner if
earth is available, an 8-Hit-Dice elemental if rough, unhewn stone is the summoning
medium. (An earth elemental cannot be summoned from worked stone, but one can be
from mud, clay, or even sand, although one from sand is an eight-dice monster.) The area
of summoning for an earth elemental must be at least 4 feet square and have four cubic
yards volume. The elemental will appear in 1d4 rounds. For detailed information about
elementals and their control see the Monstrous Compendium. The stone can be used to
summon one elemental per day.
it doesn't mention you need control or protection, and from the name of the object it seems like it gives you the control.
