Worldseeker questions

[Zoin]

I'm going to play a worldseeker in my current campaign. Level 6 teleport wizard.
My first question is in regards to the improved familiar. I'm not set on my character's alignment, but probably will be true neutral so i can take the discovery "beyond alignment" mainly for the roleplay aspect of it.
Anyhow, what would be the best improved familiar ? i'd like it to be able to fly and go invis so i can use it as a scout. Maybe have UMD as a secondary to use wands (but the WBL in this campaign is VERY low ...).
Any advice ?
My second question is in regards to planar ally : normaly, you recieve help for your deity's servants ... but my char is not a cleric/pally, and i'm not even sure he has a specific deity ... how to deal with that and planar ally ?
Lastly, the level 15 ability to get a Planar Redoubt, the description is to say the least "short"

Quote:

Planar Redoubt (Sp): At 15th level, a worldseeker creates a planar redoubt, a personal demiplane to which she can retreat to rest and plan. This functions like lesser create demiplane, except the demiplane is up to a single 50-foot cube in size and is permanent.

So, with this ability, does it cost me something to use it ? how can i reach my redoubt ? how many times per day i can use it ?

I love the idea, but doesnt seem to be that well fleshed out.
Thanks for any advice :)

Planar Redoubt is a spell-like ability; material components do not apply. It looks to me like you can create one planar redoubt only which makes uses/day irrelevant. To reach it,

create demiplane wrote:

When you finish casting this spell, you may bring yourself and up to seven other creatures to the plane automatically by joining hands in a circle. The demiplane is another plane of existence, and therefore is outside the range of any spell or ability that cannot affect or reach other planes. Creatures can only enter the plane by the use of planar travel magic such as astral projection, etherealness, or plane shift.

i.e. when you first create it you go there for free, after that you need to use plane shift or astral projection (if you put your demiplane inside the astral pane) or etherealness (if you put it inside the ethereal plane).

If you have no deity then it's up to you to either make connections with possible planar allies via roleplaying or I guess you could throw yourself on the mercy of your GM.

A flying improved familiar which can turn invisible and which a true neutral wizard could get. A cacodaemon fits, or a pooka if you'd prefer not to have a piece of ultimate evil hanging around you, or maybe a pseudosphinx if you just prefer the quiet life.

I like the cacodaemon idea because of the fact that, at least for some evil outsider familiars, they are actually created as part of the summoning, the cacodaemon will literally be a split off portion of the evil in your soul.

The thing is, it says it works like lesser create demi plane, and you can use lesser create demi plane to reach your own demi plane.

Regarding the familiar, i love the Pooka, would have been my first choice, but it's a fey, not an outsider ...

Quote:

At 5th level, she gains Improved Familiar as a bonus feat and must choose an outsider familiar that matches her alignment exactly; she can choose an outsider in this way even if it normally requires a 7th-level spellcaster as its master.

I have to take an outsider, it's clear in the description. I thought Feys where outsiders, but they're not in fact :(

Now when i read Improved familiar, it seems that with a true Neutral, you can actually choose any familiar, regardless of alignment :

Quote:

When choosing a familiar, the creatures listed below are also available to you. You may choose a familiar with an alignment up to one step away on each alignment axis (lawful through chaotic, good through evil).

Doesnt that mean i could get for exemple ... a consular imp ? (probably the best improved familiar there is)

That starts to be tricky, because having an imp serve me, might enrage some of the group members (notably a priest of Caiden Caylian)
